Ethyl lactate, an ester derived from ethanol and lactic acid, serves as a solvent in some canine flea control products. Its primary function is to dissolve and carry the active insecticidal ingredients, ensuring even distribution across the animal’s coat. Consider it as a facilitator, enabling the core flea-killing components to perform their task effectively.
The inclusion of this compound offers several advantages. It is generally recognized as safe (GRAS) by the FDA for use in food and possesses a relatively low toxicity profile compared to some alternative solvents. Moreover, it is biodegradable, contributing to a reduced environmental impact. Historically, stronger, harsher solvents were common in such formulations; the shift towards substances like ethyl lactate reflects a growing emphasis on safer and more sustainable formulations.
